(1) 180 Ohm gate resistor is not suitable for high frequencies. Reduce gate resistor in-between 10 Ohm to 22 Ohm as operation during high frequency gate requires significant current to turn on/off mosfet due to its internal capacitance.
(2) According to my experience also put resistor of 4.7k...
1.yes many of devices uses arm due to less power and higher speed.
2.its different versions of arm cores. As mentioned in post arm dnt make physical chips they only sell ip to other manufacturers. So you may find arm 7 with more or less peripherals. Like some chip having arm 7 may have 10 bit...
Hello
at this frequencies capacitive impedance is low so i think you work may be done.
If you are in country where 2MFD film capacitor easily available then try with 2uF. though 1 uF also performs well but don't use polarized capacitor obviously.
Moreover if your frequency range is from 40Hz...
Hello..
Try to put capacitor between Transformer and amplifier.
Probably 105 (1uF) High current MFR can do your work by eliminating DC component which may cause saturation of cores.
Look i am not an expert in case of megnatics but you should try it once.

Hi thanks for information.
A capacitor I am using is ceramic with dielectric NP0 which is most stable as per I know. Tolerance is 5% as of now.
Looking forward from all you guys.
HI
One more question
Which type of capacitor to be used with proximity tank circuit? Ceramic type or Film type? I doubt about ceramic as they are not performing properly . Please guide me in this
Regards
Dear all
Right now i am making inductive proximity detector.
I am using old tank capacitor 1nF 1206 (White color) i got it from old working proximity detector.
But when i place new capacitor with same value and voltage (Yellow color) in circuit it stopped working.
Can anyone help me with...
Hello all friends
I finally found the problem. Problem is in core i tried with ferrite pot core and i finally able to damp oscillations ....
Thanks for your help
Thanks for your information every replay is very useful to me.
@FVM i am putting metal near top part of core please see attached image to get clear idea about it.
I also want to mention that if i use two coils in proximity sensor then do i need to use two core (each core for each sensor)?
I...
Hello all friends
I am trying to make inductive proximity sensor.Sensing distance of 4-5mm is sufficient for me but i am not getting success in design.
As per theories provided on internet oscillations should be stopped or at least decrease when metal object in keep near coil of sensor but in...
Hi
thanks for replay.
Actually on that board JTAG connectors are provided also have some crystals as well as power supply section.
According to replay above is it mean that i can,t read bit file from xilix FPGA using parallel cable JTAG once it is programmed. Right?
i think Flash must be...
Hello all
Recently i have received Digital Printer Machine Card for repairing.It consist of FPGA XILIX Spartan XC3S200.
Now i want to check that program in flash of FPGA is corrupted or not.In simple language i want to read program from it, moreover i also want to copy program from this to...
Hello
Thanks for your valuable advice.finally I have soldered some of resistors using oven .its quite impressive for me as before I solder using hot air gun.
Maximum temperature I reach about 190C.I start from 28 C total time of soldering is 5-6 mins.
Hello all Experts
Recently i have seen many sites related to soldering SMD parts in Oven.they are mentioned that soldering temp. is about 210 C.which depends on the type of paste we are using.
I have confusion that i am using various tantalum capacitors and some transistors and ICs in my PCB...
